Title: Sustainable Solid Waste Management in India Presented by Munish Chandel
Managing municipal solid waste (MSW) is one of the significant environmental challenges for Indian cities. Open, uncontrolled MSW dumping had been the most common waste disposal practice. There is a need to remediate the old dumpsites/landfills and also identify the best MSW management practices for the present waste. I will present our work on old dumpsites/landfills, which includes the effect of ageing on the physicochemical characteristics and pathways for energy and material recovery from legacy waste. Also, I will highlight our research on waste-to-energy systems, the life cycle analysis of alternative waste management technologies, and the water-energy-GHG nexus for urban water systems.
Title: Physics-Based Models for the Advancement of Electrochemical Energy Storage Devices Presented by: Venkatasailanathan Ramadesigan
The energy sector is transitioning from fossil to renewables. Energy storage will be crucial in increasing the overall flexibility by serving multiple grid applications. The recent developments in the Electric Vehicle (EV) sector and its ambitious targets will only increase the demand for energy storage systems. This presentation will focus on two major areas: (a) Renewable grid integration of energy storage systems (large scale) and (b) Electric mobility and will discuss how physics-based modelling, simulation, model-based design and optimisation of energy storage and conversion devices can benefit understanding the underlying processes and problems for the betterment of cost, life, and safety of these systems. Additionally, a brief overview on long term energy models for an energy scenario building tool, which aims to explore a range of potential future energy scenarios for India, for diverse energy demand and supply sectors, will be presented.
Title: Hydrogen and power production through Biomass-Plastic Gasification using Waste Heat Recovery Presented by Sandeep Kumar
Biomass is a potential source of renewable energy. Agro residue and organic industrial and civic waste provides a huge potential to harvest energy from waste. Biomass gasification is a quite mature technology finding its use in various sectors. Downdraft gasification system is widely used to generate produce gas coupled with IC engine to generate electricity. Oxy-steam gasification yields syngas of high energy density (8-10 MJ/Nm 3 ). High H 2 fraction, upto 55% by volume, in syngas and its combustion characteristics motivates towards developing a more efficient gasifier-engine system. Engine studies has given promising results with reduced emissions. System developed has the capabilities to generate Syngas with varying H 2 /CO ratio. Oxy-steam gasification proved to be highly efficient system with over 80% efficiency achieved at lower steam to biomass ratio of 0.75. The high energy density in the range of 8-9 MJ/Nm 3 has been achieved which makes it better fuel compared to producer gas obtained from air gasification. Biomass gasification process provides opportunity for waste to energy and valuable chemical production and waste management in a decentralized manner.
The seminar will be followed by Q&A and a light lunch
